IMPROVEMENT IN SURFACE CONDENSERS.

Specification forming part of Letters Patent No.

163,482, dated May 18, 1875; application filed February 19, 1875.

To all whom it may concern Be it known that I, WILLIAM H. GUILD, ofWilliamsburg, Brooklyn, in the county of Kings and State of New York,have invented an Improvement in Surface-Condensers; and I do herebydeclare that the following is a full, clear, and exact description ofthe same, reference being had to the accompanying drawing, forming partof this specification, and in which- Figure i represents a verticalsection of a condenser constructed according to my invention, and Fig. 2a horizontal section thereof on the line as w.

This invention relates to surface-condensers for steam-engines and otherpurposes; and the invention consists of a novel construction andarrangement of parts, which will be fully hereinafter described, and theimprovements specifically pointed'out in the claim; a preliminarydescription, therefore, being deemed unnecessary.

Referring to the accompanying drawing,

to the upper free or scattering space of which the steam to be condensedis admitted by an inlet, 1). The base of the condenser is composed oftwo chambers, B and 0, arranged the one above the other, either one ofwhich serves to receive and distribute the condensing water to the oneset of tubes, while the other of said chambers serves to, pass oft saidwater after it has been returned through or down the other set of tubes.D are the surface condensing-tubes, projecting up within the case A.These tubes are open below in communication with the chamber B, but areblind at top. The exteriors of these tubes form the condensing-surfaces,and they are connected with the chamber B at their lower ends, byscrewing into a plate or diaphragm, d, which separates the chamber Bfrom the case A. E are the inner tubes, open at their opposite ends, andscrewing below into the bottom plate of the chamber B, so as to be infree communication with the chamber 0. These tubes project upward,

within and to nearly the top of the tubes D, but are considerablysmaller in diameter than the latter, leaving a free space around them.

This mode of independently connecting the tubes with their respectivelower chambers does away with any breaking of the joints, or packing byexpansion and contraction of the tubes, and the general construction issuch that the several tubes are free to expand or contract withoutstraining one upon the other, and the greatest facility is atforded forputting the Whole condenser together or taking it apart, the severaltubes D being collectively fitted to their places over the inner tubesE, which are likewise collectively fitted to their places within thetubes D.

G is the tube or passage for escape of the water of condensation fromthe bottom of the case A, the steam being condensed as it circulates ina downwardly direction among or between the tubes D, on their exterior,and the water of condensation being drawn ed by an exhaust-pumpconnected with the tube G. This tube is fitted to pass up throughsleeves in the chambers B O, and into the case A, and may be constructedto bind said chambers and case together.

The condensing water may either be introduced at an aperture, f, to thechamber 0 for circulation up the tubes E, and down the tubes D to thechamber B, from whence it may pass or be drawn off at an aperture, 9, orthe circulation through the tubes D E may be reversed by admitting thecondensing water at the aperture g to the chamber B, and from thence upthrough the tubes D, and down the inner tubes E to the chamber 0, andout through the aperture f. In either of such cases, however, it isdesirable to run up the discharge-pipe for the condensing water to, orabout, or above the level of the upper ends of the tubes E, to insure afree circulation of the water up the one set of tubes and down theother.

I claim- In combination with the condensing-tubes D E, rising,respectively, from the top plates of the chambers B G, the escape-tubeGr, rising from the bottom plate of chamber 0, and extending through thesame into the interior of the condenser, substantially in the mannerherein shown and described.
